Here are a few pics of Gema (the dark brindle) and Pearl. They are 15 weeks old. Gema weighs 24.8 lbs. and Pearl weighs 23.7 lbs. Our baby girls are getting big.
Often when I look at Amelia and how tall she seems I wonder if she's possibly an Olde. (not that it matters to us) but weight wise she was right in there between your girls at 24.3 lbs at 15 weeks.
They are beautiful puppies.
